Abstract
Abstract A compact intravenous fluid delivery system for intravenous injection of fluid into a patient has in one embodiment a spike, for connection to a fluid supply reservoir whose top and bottom define a vertical interval; a fluid metering device for accepting fluid from the reservoir and for displaying the flow of fluid; a fluid cannula for conveying fluid from the spike to the fluid metering device: a fluid delivery tube for conveying the fluid from the metering device to the patient; and a reservoir mounting frame for mounting the fluid supply reservoir in relation to the metering device so that the metering device is substantially contained within the vertical interval defined by the top and bottom of the reservoir. In a preferred embodiment, an intravenous tube having a length greater than 20 cm provides a conduit for passage of fluid from the fluid reservoir to the metering device. The system may include a pump mounted so that the pump and the metering device are both substantially contained within the vertical interval defined by the top and bottom of the reservoir.
